Study on Numerical Simulation of Automobile Covering Parts Stamping Forming Process
Performing the 3-D numerical modeling of the automobile covering parts by the Pro/E software,creating both addendum and blank holding surfaces,and importing them into the DYNAFORM so that a FEM model can be created.Use the DYNAFORM to perform the simulation calculation and analysis,and study the influences of the factors such as friction coefficient,die clearance and material parameters (n and r values) on the stamping formability.The results show that the parameters such as friction coefficient between die and blank,die clearance and the v value in the material parameters play the key role in the the blank flowability,and have the significant influence on the stamping result.
